The scope base is unique to the Lawton receiver. You will need to get one from them but from what I see they are extremely high quality and much less expensive then say a NF or Badger Ord rail base. A steal in my opinion. They have to front 8-40 screws and two rear 8-40s holding the rail base down solidly!

Kirby,
You will need to cut at least 1 inch off the muzzle, that's normal. If you want it to finnish at 30", you can cut more from the muzzle or the chamber end. You will want to pay attention to the flutes so you don't run out of room for a brake if you want one. Also, there isn't a blamed thing different about that barrel compared to others we put out, I was just razzing you.
Yes the bolts for the 8000s come standard with flutes. You can get them either way, just say so when you order. The 8000 actions are on par with the 7000 actions in that they are not BR actions. They are ment to be users, that said, there's nothing wrong with making a good user.
